Definitions

  • the invention relates to a dentist's seat, in particular for dental treatment, with a foot, a height-adjustable seat and at least one first joint arrangement between the foot and the seat, which is arranged in a front region of the seat and by means of which the seat is relative to the foot is held pivotably.
  • DE-OS 30 27 311 a piece of seating furniture with the above-mentioned features is known, in which the seat is connected to the fixed foot by means of a handlebar attached in the area of its two ends, the arrangement being such that when the Seat in the area of his backrest the front of the seat is raised.
  • EP-PS 0 049 310 discloses a piece of seating furniture in which the front of the seat is articulated directly to the fixed foot, the front of the seat projecting beyond the front bearing arrangement being raised when the seat is lowered in the region of its backrest.
  • the aforementioned seating furniture has the advantage over conventional dental medical dentist's seats, in which only vertical adjustment of the dentist's seat is provided, that in addition to the middle sitting position, a rear sitting position can also be assumed.
  • a rear sitting position can also be assumed.
  • there is no possibility on the part of the dentist of the front sitting posture which the dentist most frequently assumes during the treatment to support or support as needed and thereby promote a tension-free posture of the practitioner.
  • the invention is therefore based on the object of developing a handler's seat of the type mentioned in such a way that, regardless of their body size, while maintaining the desired treatment position, practitioners can always adopt an ergonomically favorable, individual, relaxed posture.
  • the dentist's seat Due to the configuration of the dentist's seat according to the invention, individual changes in the position of the dentist can be carried out without problems, the changing intake of different working postures can be effectively supported and, at the same time, the total load on the spinal apparatus can be reduced.
  • the position of the eyes of the practitioner relevant to the desired treatment position can be kept optimally according to the originally intended height by the proposed design of the joint arrangements and their movement coupling, even with a corresponding "diving movement" or a corresponding evasion of the seat position, that is for swiveling movements in the pelvic area of the dentist, which are carried out forwards or backwards.
  • treatment-related swivel movements are taken into account by the kinematic treatment seat design, but also treatment-related swivel movements in order to allow relaxed working under optimal ergonomic conditions in all relevant treatment and treatment positions realize.
  • the optimal working position for the dentist is the so-called position Zl, in which the treating dentist faces the patient without bending the body. His head is slightly inclined and his legs rest slightly apart at a height.
  • the treatment seat according to the invention advantageously provides support for the optimal working position and at the same time offers the possibility of dynamic sitting, ie. H. a change from one sitting position to another without requiring a large amount of work.
  • the user receives support from the seat padding and the backrest, which supports the pelvis at its edge.
  • This surface upholstery fulfills the supporting function in that the upholstery ventrally from the support point acts as a brake shoe, ie. H. with progressive upholstery hardness.
  • the support of the ischial humps is achieved by a hard zone in the tuber ossis ischii and, according to the buttock images, softer zones connect to the outside. This is followed by a padding with a very slight backward inclination dorsally and serves to compensate for a forward thrust, as a result of which a favorable rear sitting position is achieved.
  • the seat depth must not be too deep, i. H. the dorsal prominent parts of the pelvis must still be able to make contact with the backrest.
  • the operator's seat according to the invention takes these requirements into account in a favorable manner by means of a corresponding design and at the same time enables a change from the rear to the middle and front sitting position, which can be carried out at any time without any great work being done.
  • the user In the front sitting position, the user receives support by lowering the seat surface ventrally to the inclined plane due to the design of the first joint arrangement with simultaneous braking of the body load, which takes place ventrally via the special padding of the brake shoe mentioned. Because of the lowering the seat surface or seat shell results in the energy-saving, ergonomically advantageous self-fixation of the pelvic and trunk skeletons, a state of strength being achieved which corresponds approximately to that in yoga exercises. At the same time, the interaction of the joint arrangements ensures a desired balance by keeping the eye level.
  • a change of position within the three main seat positions, i.e. H. the rear, middle and front seat positions are promoted by the relative mobility of the seat shell to the support shell, in particular by providing a "braked" sliding ball joint arrangement. It is important that the dentist seat does not force the dentist into one position, but always fulfills supportive relaxation-promoting functions, with the seat surface of the seat shell being limited in its relative mobility during natural movement. Without such a sliding limitation, the handler would have to perform additional holding work, whereas the sliding ball joint arrangement supports dynamic sitting and the force that occurs is advantageously distributed over a larger vertebral surface.
  • the second joint arrangement and / or the first joint arrangement include a joint length adjustment by means of which the desired eye level of the practitioner can advantageously be effectively achieved even when his pelvic region is shifted.
